Is reporting spam originating from Yahoo! email futile?

Whenever I receive a spam email that appears to come from a Yahoo! Mail account, I send it off to and  About 3/4 of the time, some representative from Yahoo! rejects the spam email as having incomplete email headers.  When I forward the spam email to Yahoo! and, I include it as an attachment with full email headers. will happily accept forwarded spam if the spam has full email headers.  It will, likewise, reject any forwarded emails without the complete email headers.

Yahoo! appears to process the forwarded spam prior to sending it off to a live human.  I suspect that either this processing sometimes wrongly strips the email headers from the spam or that some of the Yahoo! support people are just rejecting the forwarded spam under the guise of "incomplete email headers".

If anyone has any ties to Yahoo!, please let them know about this issue as I’ve been getting no where with them.

Umm.. actually it did include all of the headers. How do I know this?
I forward these emails to as well as (same
message). will actively reject the message if the headers
aren't included. accepted the message.

When I forward the same message again, doing nothing different than the
first time I sent it, the message is accepted by Yahoo as it contained
the full headers. I suspect that Yahoo's automated reporting engine is
somehow truncating the email headers from time to time.

  1. Yahoo’s newest policy now rejects conventional spam reporting (as you describe above and sent to entirely. Rather they force anyone who wishes to report spam to go to a special spam reporting page on their website, paste the message headers in one place, paste the content of the message in a second-place and then duplicate an eight digit displayed code before sending the message.
    The logical effect of this far more time-consuming approach will be that far less spam is reported to Yahoo. That may be precisely the intent of course, since dealing with spam takes time but doesn’t produce revenue. On the other hand the inevitable reduction in spam reports made to Yahoo will have the ultimate effect of making Yahoo the most “user-friendly” site for potential spammers, since any such spammer is less likely to be reported by the average spam recipient due to the extra time and trouble involved.
    This is one of those policies that looks like a halfway reasonable idea until one analyzes what the likely real effect will be. In the end this new Yahoo! policy of requiring significantly more time-consuming spam reports can only reduce the number of spam reports made and thus ultimately increase the volume of spam originating from Yahoo! users. But perhaps from Yahoo!’s perspective this pales in comparison with the savings realized by reducing the cost of dealing with those annoying spam reports.
